Abstract
A comparison of the a.c. energy losses of Nb-Ti composite superconduct ors at various time intervals over several years is carried out. The o bserved decrease of eddy current losses by a factor of 1.4-3.4 is prob ably associated with increasing effective transverse resistivity of th e matrix due to diffusion between Nb-Ti and copper. The processes of a ging did not result in a decreasing current-carrying capability.
